VEGETABLE-COOKING TANK.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed May 17, 1915. Serial No. 28,750.

To all whom t may concern:

Beit known that I, DAVID M. RUSH, a citizen of the United States, residing at Buffalo, in the county of Dallas and State of Missouri, have invented certain new and useful Improvements in Vegetable-Cooking Tanks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates broadly to improvements in canning apparatus, and more particularly to devices for cooking vegetables, fruits, berries and the like, after they are packed in the ordinary cans.

The object of the invention is the provision of a cooking tank having a novel arrangement of heat conveying pipes whereby to utilize the largest proportion possible of the heat generated from the furnace beneath the tank.

With this general object in view, thein` vention resides in certain novel features of construction and combination hereinafter described and claimed.

In describing the invention, I shall refer to the accompanying drawings wherein like reference characters designate corresponding parts throughout the several views and wherein z- Figure 1 is a top plan view of a cooking tank constructed in accordance with my invention; Fig. 2 is a substantially central vertical longitudinal section as seen along the line 2 2 of Fig. 1; and Fig. 3 is a vertical transverse section through the lower'part of the tank as seen along the plane indicated by the line 3-3 of Fig. 2.

In these drawings, constituting a part of the application, F indicates the lire.-box of a furnace between which re-box and the ash-pit P, an appropriate grate Gr is disposed, the rear end of this grate being supported upon any preferred type of bridge wall W in rear of which the combustion chamber C is disposed.

The construction of the furnace so far briefly described forms no part of the present invention, but is merely illustrated for the purpose of showing the application thereof to use.

Resting upon the aforesaid furnace, is a rectangular tank 1 having solid side and end walls 2 and 3 respectively and a fluid tight bottom 4, all parts of the tank being preferably, though not necessarily, formed of sheets of blued steel. As is common with devices of this class, the tank 1 is provided with a plurality of transverse partitions 1a Disposed longitudinally of the tank 1 and projecting through the front wall thereof and through the partitions la, is a plurality of heat pipes 6 whose front ends are normally closed by caps or the like 7. In the present embodiment of the invention, two pipes 6 are shown on opposite sides of a central pipe Gawhose front end likewise pro-- jects through the front end wall of the tank l and is normally closed by a cap 7a, all of the pipes 6 and 6a having their rear ends disposed in the rearmost compartment 5, at which point the pipes 6 are threaded into nipples 8 formed on one side of a transverse and larger pipe 9 while the pipe 6a is threacL ed into a similar nipple 8a likewise formed on said pipe 9, the opposite side of the latter being provided with nipples 10 directly opposite the nipples 8 and with an additional and larger nipple 10a alining with the nipple 8a. Leading rearwardly from the nipples 10 through the rear end wall 3 of the tank 1, is a plurality of pipes 11 which constitute continuations of the pipes 6, while an additional and larger pipe 11a leads rearwardly from the nipple 10'h1 through the rear wall 3 and constitutes a continuation of the central pipe 6a. As shown clearly in Figs. l and 2, the rear ends of the pipes 11 are closed by caps 12 or the equivalent thereof, this being expedient since said caps and the aforesaid caps 7 may be removed, thus allowing the pipes 6 and 11- to be easily cleaned from time to time as necessity may require.

The pipe 11a extends to a point in rear of the pipes 11 and is at this point provided with a removable cap 12a coacting with the cap 7a for allowing the pipes 6L and 11a to be cleaned at will. The projecting rear end of the pipe 11a communicates with the lower end of an upright flue 13 which discharges into the stack S rising from the combustion chamber C.

As clearly shown in Figs. 2 and 3, the numerous longitudinally disposed pipes as Well as the transverse pipe 9 are located contiguous to the bottom i of the tank 1, and at predetermined points, branches 14 lead through said bottom and communicate With these pipes, it being therefore evident that the heat generated from the furnace Will not only act directly upon the bottom 4: of the tank 1, but Will rise to a considerable degree through the branches 14 and into the several longitudinal pipes. .From the latter, this heat Will travel through the transverse pipe 9 and will be discharged therefrom through the pipe 11a and the flue 13, into the stack S, the passage of heat being readily controlled by shiftable dampers (not shown).

rlhe branches 14 are here shown in the form of nipples depending from Ts on the various longitudinal pipes, said nipples being passed through the bottom of the tank and having nuts contacting With the upper and lower sides thereof. If found necessary, gaskets or the like may be interposed between the nuts and the bottom, such additions lying Within the skill of the manufacturers of the device.

It is to be observed that more radiating area is provided in the rearmost compartment 5, this being particularly expedient if the transverse pipe 9 is not connected With the combustion chamber C by means of the branches 141, since it is evident that the additional radiating surface of the large pipe 9 Will counteract the loss of heat that might occur by passage through the other branches 14:.

From vthe foregoing description, taken in connection with the accompanying drawings, it will be evident that although very simple construction has been provided for accomplishing the desired end, the complete device Will be highly eiiicient in operation and Will possess a number of advantageous features.

claim:

The combination With a furnace having at one end a iire box, and at its other end a smoke flue, and a tank resting on said furnace and provided with a number of transverse partitions dividing it into a number of compartments; of a transverse heat pipe in the compartment remote from the fire box, nipples depending from said pipe and opening into the furnace, an outlet pipe4 from said transverse pipe into the smoke iue, a plurality of longitudinal heat pipes passing through the several compartments and delivering into the transverse pipe, and a plurality of nipples depending from said longitudinal pipes and opening into the furnace.

ln testimony whereof il have hereunto set my hand in presence of tivo subscribing Witnesses.
